Veo 3.1 is Google text-to-video model, reached through Google Flow, the creative studio at labs.google. It generates video with native audio, meaning dialogue, ambient sound and effects come out of the same generation rather than being added afterwards. Output is up to 1080p.
Access works through Flow credits on the Google AI plans rather than a separate subscription. Google AI Plus at 4.99 dollars a month includes 200 Flow credits. Google AI Pro at 19.99 dollars a month includes 1,000 credits and, per Google own FAQ, a limited trial of Veo 3.1 Lite rather than the full model. Google AI Ultra at 99.99 or 199.99 dollars a month includes 10,000 or 25,000 credits and full Veo 3.1. Flow is also available on the free tier with limited access.
The practical catch is that the tier most people buy, AI Pro at 19.99, gives a trial of the Lite model rather than Veo 3.1 proper. Full access starts at the Ultra tier, which is a different price bracket entirely. Google also runs a faster, cheaper companion model called Gemini Omni Flash for short clips of three to ten seconds at 720p.
Credits do not translate to a fixed number of videos. Cost per generation varies with duration, resolution and whether audio is on, so a credit balance is not a clip count.
